Hydraulics library
The Hydraulics library (HyLib) is a powerful yet simple-to-use tool for the modeling of hydraulic systems using mineral or synthetic oil. Applications include machine tools, automatic transmissions, actuation systems and open or closed circuit drives used in, for example, excavators or forklift trucks. There is a seamless integration of the Hydraulics library with other Dymola libraries.
The Hydraulics library provides basic models for the modeling of pumps, motors and cylinders, restrictions and valves, hydraulic lines, lumped volumes and sensors. Users can connect components freely as they desire, so it is easy to realize non-standard configurations. Contrary to special-purpose tools for the same type of simulations, the Hydraulics library also has open source code in Modelica so that the available models can be duplicated and modified to fit user needs. The models can also be used for real-time and hardware-in-the-loop applications.
For standard applications these classes cover all needed components. If, however, specially designed components are used, these can be easily modeled by modifying library components. All relevant effects, like spool forces, metering orifices, pressure dependent bulk modulus, are available as sub-models.
The modeling concept allows hydraulic components to be connected in an arbitrary way – e.g. in series or in parallel – just by drawing connection lines, no special components for splits or mergers are required.
